Code: Quarry - 4 Level Demo

I know we are mostly multiplayer-based. But hey, why not get something out there that some people may like. I'm working on a singleplayer level-set. These are the first 4 levels of 32. I plan on putting things in these levels that people don't really do. Outdoor looking areas, more doors to try and get passed besides the normal blue, yellow, and red.. Possibly a few more things. It's just a work in progress. So tell me what you think if you try it out!
